ABSTRACT:
A radio paging receiver enables an user of the receiver later to see a received message even when an alert stopping operation or message confirmation operation is first executed in an environment too dark to see the received message. The receiver has a photosensor for detecting whether a display environment is light or dark. If the alert stopping operation is executed in the dark condition, the received message is stored in a memory as an unconfirmed message, so that the user later can see and read the received message in a light condition after a change of the environment. In addition, when the environment is changed from a dark condition to a light condition, if an unconfirmed message exists in the memory, the receiver alerts the user.
